Keep reading fairly negative comments about this PSU. I sort of regret buying it when I could have gotten a TX750v2 for $10 cheaper. It worries me when like 50% of newegg reviews claim it failed on them after few months. It's almost like a rival company told all it's employees to buy this model and write bad reviews.. that how eerily similar the negative comments sound. It hasn't failed yet for me but I'm about to add a second 670 to my rig. Do you guys think it will be able to handle it? I'm running IB@4.4 and plan to put a modest OC on the 670s.
 
Don't know about the TXxxxM series, but I know that if I were to buy a PSU today to replace my TX750, I would find a good modular PSU. The amount of unused cable I have to try and hide is absolutely ridiculous.

That's another negative about the 750M, it's not really modular as advertised. I'd say it's only 40% modular.
 
Assuming that you didn't get a bum TX750M, you should be ok with a second GTX 670. Though you honestly won't know if there's an issue with your TX750M until you really load it up.
 
So far holding up well with both cards set at 122% TDP. Ran my system through this Wattage calculator: http://www.thermaltake.outervision.com/Power

Recommended PSU requirement was 483W. That's including 2x GTX 680s because 670s are not on that page yet. OCed CPU was factored in too. Much less than I expected.

My personal calculations beforehand went like this:

Geforce 670 = 175W * 1.22 * 2 = 420W
Core i5 3570k @ 4.4/1.27 = 110W
4x case fans + CPU fan = 25W
USB external hard drive = 5W
8gb ram = 10W
Motherboard = 10W
SSD = free

Total: 580W

So plus 100W for headroom gives 680W PSU requirement but apparently my calculations were off.
